Study of an Oral Fluid Testing Approach

The purpose of this study is to identify and evaluate oral fluid testing as a biologic measure of cannabis use days that can be assessed remotely. The researchers will conduct this fully virtual study among a community sample of 200 individuals aged 18-30 years who have used cannabis at least 1 time per week on average in the past 30 days. Participants will complete oral fluid (saliva) tests, urine tests, and Timeline Follow-back interviews (self-report) that indicate their recent cannabis use (delta-9-THC). Participants will present for 3 virtual study visits across \~3-4 weeks and be asked to complete activities in between: Study Visit 1 (Day 0; informed consent, baseline survey, TLFB interview), Study Visit 2 (\~Day 7; TLFB interview, urine testing), 6 days of at-home videorecorded oral fluid testing, Study Visit 3 (\~Day 21; TLFB interview, urine test, oral fluid test, survey, interview).
